Send and receive SMS by email with our email to SMS platform

Email to SMS

What is the email to SMS service and how does it work?

The email to SMS UK gateway allows you to use email to send and receive SMS messages. Emails are sent in a specific format and arrive on the recipient's phone as a text.

If a reply number has been set up, then the recipient can also reply to the text, which is then converted back to an email and delivered to your email inbox.

Three simple steps to get up and running


Set up a free Account

If you're a UK company, your account comes with 50 free text credits for testing.

Contact The SMS Works to authorise the domain or domains from which you'll be sending your email.

The domain is the part of an email address that comes after the @ symbol. Free email domains are excluded from the service.

Purchase some SMS credits

The minimum order is £10 + VAT, at 3.95 pence per SMS credit.

How to send email 2 sms

Formatting the email address

Sending text messages using the email 2 SMS gateway is simple and quick. All emails need to be in plain text format. HTML emails will be rejected and messages will not be sent.

The format of the address is as follows:

  • [email protected]. The first part of the email address, '07900122321', is the mobile number to which you want your text to be sent. The second part, 'senderID' is who the text message is from.
  • The Sender ID should be a maximum of 11 alphanumeric characters or 15 numeric characters. No spaces are permitted. If you want to receive replies to your messages, you can use an SMS Works Reply Number as the sender ID.
  • If no sender ID is specified, an error message will be sent to you by email detailing the issue. If you have a reply number set up up in your account, that can be set as the default sender ID, if you ask us to specify it.

Formatting the message content

The message content itself goes into the body of the email.

A standard text is 160 characters and uses 1 text credit in the UK. You can send text messages of up to 1280 characters in length. Longer text messages use more than 1 text credit.

To indicate where the message content ends, finish your message with the characters ##

This tells us where the text message ends and prevents the sending of email signatures or anything else that appears at the end of your emails.

Use an SMS Reply Number

A virtual mobile number (or 'SMS reply number') allows you to receive replies by SMS, which are forwarded to you by email. Virtual mobile numbers are quick and easy to set up and cost £13.50 + VAT per month. A free, 7-day trial is available.

The reply number can be specified as the Sender ID on your email to SMS. Alternatively, we can set a nominated reply number to be your default sender ID, which means it can be omitted from the email address each time you send.

Reply Forwading

When the recipient replies to a text, it will be routed back to the forwarding email address that is configured on the SMS reply number. You can manage this from your account. We'll forward the following content to you:

  1. Mobile number of responder

  2. Date and time of their text

  3. Content of their message

  4. Content of the last outbound message you sent to this recipient, for context

Some things to consider


Email can be subject to delay

This could be a problem if the SMS you are sending are time critical.

More third party data processors

Sending SMS by email inevitably means that more organisations will be processing your data. This could be an issue if the nature of the texts are sensitive or if you are required to log data processors under GDPR regulations.

More data is stored in different places

Email is stored in your email client outbox, so there’s reasonably high exposure of the message sent. This could potentially present a data security risk.

Are there any disadvantages with Email 2 SMS?

Sending text messages directly from your email does have a few drawbacks. None of them are major issues but it’s a good idea to be aware of some of the minor drawbacks.
